PowerTech 71767 User manual

  • Hello, I am a chat assistant and I have read the Instruction Sheet for the POWERTEC Precision Miter Gauge model 71767. This document covers assembly, adjustments, and usage instructions including how to set angles and use the miter gauge with a fence. I'm ready to answer any specific questions you have about it.
  • What should I do before making adjustments to the Precision Miter Gauge?
    What are the common angles that have positive stops?
    How do I adjust the miter bar for side movement?

WARNING
Risk of accidental starting and serious personal injury.
Unplug the machine before attaching the Precision Miter Gauge.
ASSEMBLY Refer to Figures 1, 2
No additional tools needed.
NOTE: This miter gauge is equipped with a Locking Plunger
with spring loaded pin. The most commonly used angles are
notched with positive stops 0°, 15°, 22.5°, 30°, 45° and 60°.
To set or change the angles see TO USE on page 4.
Figure 1
See Figure 2. Place washer onto handle threads and thread the
handle onto the guide bar. Tighten handle.
Figure 2
Model No. 71767
23-0228
SETTING THE GAUGE TO 90° See Figure 3
NOTE: The Miter Gauge arrives factory calibrated.
For convenience, a Fence (not included) can also be used to verify
perpendicularity to the miter bar.
1. Align both the Miter Gauge Head and Indexer to 0°.
Lock the Adjustment Plunger.
2. Use a square to verify that the miter bar and miter gauge face
are perpendicular.
Figure 3
If not square or requires resetting:
Use the included 3 mm hex wrench to loosen the four screws on
top of the miter head. Back out the two screws on bottom of miter
gauge face. Use a square to set the face perpendicular to the miter
bar. Re-tighten the four screws on the top of the miter gauge. Run
the two screws, on the bottom face of the miter bar, in until they
just touch the miter gauge head. Use a square to verify the face is
still perpendicular and did not shift.
NOTE: Once the miter gauge face is square to the bar, no
other adjustment is required. If by chance the workpiece is not
square, use a square to square the miter gauge face directly to
the blade or follow the instructions supplied with the machine to
square the machine's miter slot to the blade.
FITTING MITER GAUGE TO MITER SLOT
See Figures 4, 5. If the tool is equipped with a T-slotted miter
slot, use the 3mm hex wrench (included) to ensure the screw
holding the miter bar plate is tight. If the tool is not equipped
with a T-slotted miter slot, remove the plate. Save this part.
Figure 4
Place the miter bar into the miter slot on the saw table and
check for side movement. If the miter gauge guide bar moves
freely through the miter slot and has no side-to-side play, no
adjustment isneeded.
If adjustment is needed:
Use the four expansion discs located on the top of the
miter bar to adjust any side movement. Use the 2.5mm hex
wrench (included) to tighten the screws until all side motion
is removed. Turn the screws clockwise to tighten the t and
counterclockwise to loosen the t. Ensure the bar slides freely in
the miter slot.
Figure 5
TO SQUARE THE MITER GAUGE FACE
See Figures 6, 7. The miter bar features an adjustment screw that
allows the miter gauge face to be set perpendicular to the table.
To Check:
1. Set the indexing lever to 0° and engage the spring loaded pin.
2. Tighten the handle and place the miter bar into the miter slot.
3. Use a square to check the perpendicularity of the face to the
table. If square, no adjustment is needed.
NOTE: Check can be made with or without a fence installed.
Figure 6 (Shown without Fence)
If adjustment is needed: See Figure 7
1. Remove the miter bar from the miter table slot and ip over.
2. Loosen the handle.
3. Locate the adjustment screw on the bottom of the miter bar,
adjust with the 3mm hex wrench (included).
NOTE: If the gap is at the top of the miter gauge face, tighten
the adjustment screw. If the gap is at the bottom of the miter
gauge face, loosen the adjustment screw.
4. Tighten the handle and recheck. Repeat until square.
Figure 7
INSTALL ONTO A FENCE (Not included)
This Precision Miter Gauge is designed to work with
POWERTEC and DuBois Fences (not included). It can also be
used as a conventional Miter Gauge on various other fences.
Figures 8-9 Shown using POWERTEC 71768 Fence
(Sold separately)
1. Remove Fence Lock Knob. Loosen the two 5/16" Round
Knobs on the Miter Gauge and slide the T-bolts into the
Fence slot.
Figure 8
2. Tighten 5/16" Round Knobs on Miter Gauge. Reinsert Fence
Lock Knobs and tighten to secure in position.
Figure 9
TO USE
See Figure 10. Loosen the Handle. To unlock the Adjustment
Plunger pull and twist left (counter clockwise). Release. Plunger
is now in neutral position. The Miter Gauge will now move freely
side-to-side.
Figure 10
CAUTION
Always keep Adjustment Plunger in UNLOCKED position when
moving set pin to any location. Failure to do so may result in
damage to the Miter Gauge.
If desired angle is a positive stop, pull Adjustment Plunger and
twist right (clockwise). Allow set pin to drop into notch of the
desired positive stop. Release the spring loaded plunger to
secure into place. Tighten the handle.
If the desired angle is not a positive stop, maneuver Miter Gauge
to desired angle and tighten the handle.
For Example:
The protractor scale on the Miter Gauge head acts like a Vernier
scale and precise angles can be set.
1. Loosen the handle and unlock the adjustment plunger.
2. Figure 11 shows the gauge set to 25.3 degrees. Zero is past
the 25 degree mark and the upper and lower scales line up 3
marks past zero on the lower scale.
3. In Figure 12, zero is past the 18 degree mark and the upper
and lower scales line up 7 marks past zero on the lower
scale, for a measurement of 18.7 degrees.
4. When the angle is set, tighten the handle.
